have invented newand useful Improvements in Horseshoe-Calks, of which the following is a specification. I v

f Our invention relates to improvements in calks for horseshoes; and it consists in the of devices hereinafter describedand claimed.

One object of our invention is to effect imprpvements in the construction of the toeca k. I I

A further object of our invention is to pro- ;vide a coupling device which is'adapted to be used, in combination with the toe-calks to i I prevent the latter from turning and to keep them in linewith'each other. I

In the. accompanying drawings, Figure 1 is a perspective View of a horseshoe provided with our roved calks and coupling device. Fig. 2 is a etail'perspective view of, one of the toe-calks. Fig. 3 1s -.a similar view of the coupling device, and Fig. 4 is a similar view of a bar or summer cal k. r

The improvedtoe-calks shown in Figs. 1 and 2 are each formed of a bodyportion '1, made of iron, and having on its under side at its center a screw-threaded stem2 to engage'a screw-threaded opening in thetoe of the shoe. The body portion 1 of each toecalk is formed with oppositely-extending reinforcing V-shaped webs 4, the sides of base-flanges 3 and'at its center'portion with which converge outwardly. The sides of'the body portion are parallel, or' substantially I so, for a suitable distance from the basefianges 3, and. the outer portions of the said sides converge'inwar'dl as at 6; The body ortion of each toecall is provided with a ongitudinal recess 7, in whichis placed a steel blade or center portion 8,.which extends jects outwardly therefrom and has its outer edges'beveled toward each other, as shown.

The 'toe-calks when they are secured to-the ,calks, the said coupling device bearing on the I base-flanges 3 of t e toe-'icalks and the oppo at 15, and are widened near their outer edges, I

the screw-threaded stem or stud being prei from end to'end of the body portion and proshoe are spaced apart and between them issite sides of its recesses 10 being provided I with roughened surfaces 11, which cause the said coupling device to bite firmly on the said toe-calks, so that the same is prevented from oopf the coupling device prior to the ap lica tion of the coupling device to the toe-ca ks is slightly less than that of thespaces between the parallel sides 5 of the toe-calks, so that when the coupling device is drivenont'o the body'porti-ons of the toe-calks the same be, comes firmly secured thereto, as will be un- 'dersto-od.

Each of our improved heel-calks 12 is l1ollowed on three sides,as at 13, to provide three" radially-disposed wings 14. The said wings are narrowed toward the center of the'calk, as

as at 16,.their extreme outer edges being o positely beveled, as at 17. Each heelca kis formed at its inner end with a screw-threaded shank or stud, which engages a screw threaded opening in one of the heels of-the shoe to secure the calk thereto. By. thus narrowing the inner portions of the wings or blades of the heel-calks the same are ad apted to more readily cut into the ice to prevent the horse from slipping.

The form of our improved toe-oalk shown in Fig. 4 is adapted for use in warm weather.

The same is bar-sha ed -that is to-say, is of oblong rectangular orm.and is provided at its corners with rectangular recesses 19 to e engaged by the recesses in the ends of the coupling device. This form of our improved toe-call; is made, preferably, entirely of steel,

erably formed integrally with the bar or head portion of the cal From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more'extended ex; lanation. I

Various changes in the orm, proportion, and the minor detailsof construction may be resorted to without departing from the principle orsacrificing any of the advantages of this invention.

Having thus described our invention-,what we claim as new, andv desire to secure by Letters Patent, is.- 1. A horseshoe having detachable .toecalks, in combination with a coupling device 9 provide end flanges 20, which are adapted to scribed.

having recesses in its ends to engage the 0pposing ends of the toe-calks and prevent the latter 'fronr turning, substantially as de- '2. A toe-call; comprising a bodyhaving' substantiallyparallel sides, outwardly-extending, base-flanges, strengthening-webs in the n ngies between the sides and base-flanges, av recess between the "sides, and a blade in said recess, substantially as described.

3. A horseshoe having toe-calks provided with baseflanges, in combination with a coupling device bearing on the base-flanges of the calks andhaving recesses in its ends to receive the opposing end portions of the calks, sald coupling device preventing the I calks from turning, substantially asdescriberl. In testimony whereof we have signed our names to thls specification in the presence 01 two subscribing witnesses.
